Product Number: MAX20446
Hi,
We are using MAX20446 in our program for backlight control.
PWM is set by I2C interface. In the datasheet, there are 3 registers provided for setting the PWM duty.
The default value of TON is 0x3FFFF and the default duty would be 99.99%
The default duty is calculated as per below formula.
TON=(TONH≪10)+(TONM≪2)+TONL
Is our understanding correct?
if i want to set 50% duty, i need to set TONH = 0x80, TONM = 0, TONL =0, TON = 0x20000. Is this correct?
Please share the correct procedure if above calculation is incorrect.
Thank you.
Regards,
Viswanath
